ʻO Graphite kahi allotrope o ke kalapona, he aniani kuikawa ma waena o nā aniani ʻātika, nā aniani a me nā aniani moleola. He ʻeleʻele hina ʻeleʻele, ʻano palupalu, ʻano momona. Hoʻonui ʻia ka wela i ka lewa a i ʻole oxygen e kuni a hana i ka dioxide kalapona. E hamo ʻia ia e nā ʻākena oxidizing ikaika i loko o Hoʻohana ʻia ma ke ʻano he ʻūlū antiwear a me nā mea lubricating, e hana ana i ka ipu hao, electrode, pākeke maloʻo, kēpau penikala. Ka laulā o ka loaʻa ʻana o ka graphite: graphite maoli, graphite aniani crystalline, graphite flake, graphite cryptocrystalline, graphite pauka, pepa graphite, graphite hoʻonui ʻia, graphite emulsion, hoʻonui graphite, pālolo graphite a me ka conductive graphite pauka, etc.
1. ke kūpale kū wela kiʻekiʻe: 3850 ± 50 ℃ ke kiko hoʻoheheʻe o ke kiʻi, ʻoiai ma hope o ke ahi wela kiʻekiʻe loa, heʻuʻuku ke kaupaona, heʻuʻuku ka nui o ke koina hoʻonui hoʻonui wela. Hoʻonui ka ikaika o ka graphite me ka hoʻonui ʻana o ka mahana. . Ma 2000 ℃, ka ikaika o ka graphite papalua.
2. conductive, conductivity thermal: ʻo ka conductivity o ka graphite he hoʻokahi haneli mau manawa ke kiʻekiʻe ma mua o ka mineral non-metallic ore. ʻO ka conductivity thermal o ke kila, hao, kēpau a me nā mea metala ʻē aʻe. Hoʻoiho ka conductivity thermal me ka hoʻonui ʻana o ka mahana, ʻoiai loa. wela kiʻekiʻe, graphite i loko o ka hoʻonani;
3. lubricity: ka lubrication hana o ka graphite hilinaʻi nui i ka nui o ka graphite flake, flake, friction coefficient ʻoi aku, ʻoi aku ka maikaʻi o ka lubrication hana;
4. kumupaʻa kūpaʻa: graphite ma ka mahana wela i kū pono kemika paʻa, ʻakika kūʻē, alkali ia'ku a me ke aloha'ūhehehehehe kahe ka popopo;
5. plasticity: maikaʻi ka paʻakikī graphite, hiki ke wāwahi ʻia i kahi pepa lahilahi loa;
6. kūpilikiʻi kūpilikiʻi wela: graphite ma ke ana wela o ka lumi ke hoʻohana ʻia hiki ke kū i nā loli nui o ka mahana me ka ʻole o ka poino, ka hoʻololi ʻana o ka mahana, ka loli o ka graphite e loli iki, ʻaʻole e haki.
1. kālailai haku mele: kalapona paʻa, ona mau, haumia, a pēlā aku.
2. ʻIke hoʻāʻo kino: paakiki, lehu, viscosity, fineness, huna nui, volatilization, kikoʻī umekaumaha, kekahi ʻilikai wahi, heheʻe wahi, etc.
3. ka hoʻāʻo ʻana i nā pono mechanical: ka ikaika o ka ʻumeʻa, ka brittleness, ke kūlou ʻana, ka hoʻāʻo ʻana.
4. ka hoʻāʻo ʻana i ka hana kemika: ke kūpaʻa o ka wai, ka paʻa ʻana, ka waikawa a me ka pale alkali, kūpaʻa ka popopo, ke kūpale ʻana i ka wā, ke kūpaʻa wela, a pēlā aku
5. Nā huahana hoʻāʻo ʻē aʻe: conductivity uila, conductivity waiwela, lubrication, kūpaʻa kemika, kūʻē kūpilikiʻi wela
